Ceramic Extrusion Die Design

Initial costs and lead time of aluminum extrusion tooling is usually a good deal lower than the tooling required for alternative technologies like die casting steel roll forming vinyl extrusion impact extrusion stamping or pultrusion.

Ceramic extrusion die design.

Being electrically conducting syalon 501 can be electro discharge machined which allows complex die profiles to be formed economically. Understanding the difference metal and ceramic extrusion dies is key to successful application of ceramic dies. Extrusion picture supplied by barwell limited.

A typical extrusion operation will make use of a die assembly including the die. Click here for representative cost and lead time comparisons. This material is syalon 501 a composite sialon ceramic. Demonstration video wherein honeycomb shaped monoliths and profiles were easily extruded using local natural clays without the need of chemical binders.

Extrusion and drawing dies are also available in an advanced ceramic which uniquely is electrically conducting. This forming process consists of forcing a plastic mix of a ceramic powder through a constricting die to produce elongated shapes that have a constant cross section. Magnesia stabilized zirconium oxide extrusion dies from zircoa inc are engineered to provide the high temperature stability chemical inertness hardness wear and corrosion resistance required to extrude non ferrous alloys such as copper copper nickel brass and other copper alloy. English ceramic extrusion dies outperform traditional dies in both direct and indirect presses.

Dynamic ceramic manufactures both finished custom made extrusion dies or blanks that can be finished in your tool room. This allows the ceramic to flow freely thru the die with or without heating or vacuum. Dynamic ceramic s flexible approach to manufacturing and technical support is unequalled in the ceramics industry. The computer controlled extrusion facility suitable for making ceramic tubes with varyingly controlled bends was designed to comprise four main features.

The powder mix consists of a fine ceramic powder with the appropriate additions of binder s and plasticiser s to. During this time a vast body of empirical knowledge concerning the design of augers dies and machines to do particular jobs has grown. The raw material loaded into a ceramic extrusion machine is usually fine powder with a combination of additives in the form of binders and plasticizers to impart the desired rheology.
